Hey guys I'm obviously new to this forum, I'd greatly appreciate ya'll clearing something for me. My friend's convinced that you can bolt a D16Z6 head to a D15B6 (HF) motor, altho I do recall reading in a different forum that you can't do that cause of valve clearance issues. So that would be the question can you use a Z6 head with a B6 block (I do beleive it comes with either a 8 or 12 valve head) or will I blow my motor by trying to run that setup? Any answers would be appreciated, in depth explinations would be greatly appreciated. I did search the engine building forums and couldn't find an answer.
